Chapter 4.4, Problem 1CR
Summary Introduction
DNA is a genetic material in both prokaryotes and eukaryotes. Generally, DNA is found in the double helical structure in the genome. Synthesis of DNA is known as replication and it is an important phenomenon in the central dogma of biology. In replication, two identical copies of DNA molecules are produced from the single DNA molecule.

What are cis acting DNA sequences? List them
What is the base sequence, specified in the 5′-to-3′ direction, for a segment of newly formed DNA if it was formed using the following template DNA segments?
3′ AATGC 5′
5′ AATGC 3′
3′ GCAGC 5′
5′ GCAGC 3′
In the drawing shown below, the top strand (purple) is the template DNA, and the bottom
shows the synthesis of the lagging strand (DNA in blue and RNA primers in red).

After DNA polymerase I removes the middle primer and fills in with DNA, where is DNA ligase
needed? See the arrows on both sides of the middle primer. Explain whether ligase is needed at
the left arrow, at the right arrow, or both?
